IMPROVEMENT IN HORSE BAH-FORKS.

. Schedule referred to in these Letters Patent and making part of the same- To allwhmn it may concern Be it known that I, E.-J. EENN, of Medina, iu'the county of Medina, and State of Ohio, have invented a new and useful Improvement in Hay-Forks; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference hein g had to the accompanying drawings, forming part of this specification.

This invention relates to new and useful improvements in forks for handling hay, and consists in operating two tines, by means of a bar and lever and their connections, as hereinafter described.

In'the accompanying sheet of drawings- Figure 1 represents alongitudinalview of the fork, showing the'tines closed.

Figure 2 is a view of the fork, showing the tines extended.

Similar letters of reference indicate corresponding parts. 3

Ais the shaft, which is semi-tubular, with its lower portion expanded, to give room for the rack and sectorgears, on the ends of the bar and tines.

B is the rack-bar, which works longitudinally within the shaft A, seen in dotted lines in the drawing.

The lower portion of this bar forms a double cogged rack, which engages with the cogs on the inner ends I of the tines.

O and I) are the tines, which are pivoted to the expanded portion of the bar, as seen at a e.

It will be seen that when the rack-bar B is moved up and down in the shaft, the tines will, by virtue of with the bar 13 thereby, by means of the connectingplates 1. r

The pivot J, by which those plates are connected with H, plays in the slot in the plate H.

' In fig. 2 the tines are extended, the bar 13 being thrown down by elevating the lever F.

In this position the pivot J bears on the lower end of the slot, with the connectiug-plates I standing pan allel with the bar, and with the top end of the bar directly beneath the lower end of the lever.-

In this position the fork may be lifted with the tines loaded with hay, and the tines will retain this position until the'lever F is depressed, when the tines will drop and discharge their load.

The operation will be readily understood from the drawing.

One of the tines, O, is slightlylonger than the other, which allows them to be extended when the fork, as seen in fig. 1, is thrust into the hay on a floor.

In mowing away hay, or 'inraising it for any purpose, the fork in suspended from any suitable fixture, by means of a rope passing over a pulley attached to the ring K, in .the top of the shaft.

Then the fork with its load has been elevated or carried to the desired position, the lever F is depressed, by means of a cord secured to the lever at L.

The pivot J of the connecting-plates I holds the tines closed when bearing upon the upper end of the slot in the rack-bar, and holds them open when hearing on its lower end, both positions being represented in the drawing.

Having thus described my invention,

1 claim as new, and desire to secure by Letters Patent 1. The lever F, in combination with the connectingplates I and slotted plate H, arranged and operating substantially as and for the purposes described.

2. The combination of the lever F, the bar B, slotted plate H, the connecting-plates I, and the tines O D, with the shaft A, constructed, arranged, and operating substantially as and for the purposes described.
